Yes, but if you don't fit within that formula, you're going to pay an extra tax if you don't actually use what you're getting. I think if you can meter where it's going to cost you out, you can also meter it back if it isn't used.
I do want to follow up with regard to your investments. I know that Bell has been doing extremely well. I think the profits for BCE were up 85% for 2008-09. You were talking about the $3 billion you invested, but how much of that investment is from the deferral accounts?
